PLOW ATTACHMENT.

Application filed September 22, 1922. Serial No. 589,927.

T 0 all whom it may concern Be it known that we, Ginnoiv Ii. NOBLES andWVILLIAM F. Noenns. citizens of the United States, residing at LoneGrove, in the county of Llano and State of Texas, have invented new anduseful Improvements in Plow Attachments, of which the following is aspecification.

This invention relates to farming iinple ments, the general object ofthe invention heing to provide means for attaching a shovel or the liketo its standard.

This invention also consists in certain other features of constructionand in the combination and arrangement oi? the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim. 7

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the sev eral views and in which Figure lis a fragmentary view of a part of a cult' ator showing our invention inuse.

Figure 2 is a sectional view.

Figure 3 is a bottom plan view of the shovel.

Figure 4 is a cross sectional view through Figure 2.

In these views 1 indicates the standard of the implement and 2 theshovel or tooth thereof. In carrying out our invention we provide thestandard with a wedge-shaped slot 3 and with an. inclined notch t ateach side of the slot. The standard is also provided with a hole 5 whichcommunicates with the upper inclined partof the slot. The shovel ortooth is provided. with a wedged part 6 for engaging the slot and withan inclined projection 7 on each side of the wedge for engaging thenotches. The upper edge of the wedge is provided with a semi-circularrecess 8 which will register with the hole 5 when the parts a re placedtogether. A pin 9 is adapted to he passed tlii-ou gh the ho le to engagethe recess to lock the wedge in the slot.

From the above it will be seen that the shovel is firmly locked to thestandard and that no movement can take place between tl standard and theshovel the shovel. In order to detach pin must he knocked out and thenthe shovel can be moved away from the standard. in order to pull thewedge and proons from the slot and recesses.

All strain is taken by the inclined walls of the parts so that there i sno danger of breaking the scription that theadvantages and novel featureot the invention will be readily apparent.

h s desire i t to he understood that we ma make changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appended.claim.
